Error 500 not logging & empty tmp Directory

[JosNas]

I am getting an Error 500 in both of my Espo instances on Cpanel whenever I try to change something like deleting a field. However nothing is logging in the log files but the tmp folder is showing like a change happened but I find it empty when I enter it. How can I solve this issue?

In case there is no log in espoCRM, see if there is an Apache log in your cPanel. Maybe you find something there. Whenever I get 500 error it is mostly from a database error.

The problem is it was working fine. I don't think it's from the database i think it is related to the configuration. Whenever i click clear cache from Administration, metadata.php gets wiped clean. Even if I try to install a new EspoCRM I get an Error 500

Update: the error I found is:

` [16-Nov-2021 14:59:22 UTC] PHP Fatal error: Illegal length modifier specified 'f' in s[np]printf call in /home/n6dd4d5/public_html/go/hausmangas/admin/application/Espo/Core/Utils/File/Manager.php on line 308 `

What could be causing it and how to solve it?

Seems to be a PHP error:

I got the code for metadata.php back from a previous version but now it's telling me Entity Workflows doesn't exist which is worrying because I purchased and paid for the advanced pack. I still have the license and proof of purchase
